Feature:
1. Only one measurement is needed to find out the connection of the full bridge. The test time is about two seconds, only capacitance and inductance measurements will take a long time.
2. Support the measurement and symbol display of two resistances, up to four digits and unit display.

Specification:
Item Type: Transistor Tester
Material: Aluminum alloy
Model: LCR-T4

Note:
1. All functions are only used for microcontrollers with more program memory, such as ATmega168. The resolution of resistance measurement is 0.1 ohms, and the highest measurement value is 50M ohms.
2. LED is detected as a diode, and the forward voltage drop is much higher than normal. The double light-emitting diode is detected as a double diode. It is possible to show signs of the correct direction for two diodes.
3. If the test current exceeds the holding current, SCR and triac can be detected. However, some semiconductor thyristors and triacs have higher trigger currents than the tester can provide. The available test current is only about 6mA!
4. Optional equipment calibration port output internal resistance and zero-offset self-test capability measurement (ATmega168). A 100nF to 20uF capacitor is required to connect between pin 1 and pin 3 to compensate the offset voltage of the analog comparator. This can reduce the measurement error of capacitors above 40uF. The internal correction voltage reference voltage with the same capacitor was found to adjust the gain of the internal reference measurement ADC.
